EDWARD G. BUDD, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO HALE-KILBURNMETAL COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OFPENNSYLVANIA.

SE AT-FRAME T 0 all whom it may concern:

Be it known that I, EDWARD G. BUDD, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia andState ofPennsylvania, have invented certain new and useful Im rovements in Seat-Frames, of which the fol owing is a specification.

This invention relates to seat-frames and more particularly to framesadapted for use with seats of the type now commonly em ployed in cars.

The object of the invention is to provide a structure suitable forsupporting one end of such a seat which is of simple construction andornamental appearance, which possesses ample strength, though occupyingcomparatively small space, and which consists of few parts arranged sothat they can be readily assembled and will be held securely inposition.

A seat frame constructed in accordance with my invention consistspreferably of a hollow pedestal of pressed sheet-metal arranged forsecuring itupon a floor or other support and a yoke supported onbutseparab e from this pedestal and arranged to carry the connectingrails on which the parts of the seat are mounted. The yoke carrying theconnecting rails has a hollow portion preferably formed integraltherewith and of the same dimensions as the portion of the hollowpedestal on which it rests and is detachably mounted on the edestal bysecuring within the end of the latter, as by brazing or riveting, ametallic band or collar whose upper edge extends beyond the end of thepedestal and' over which the open end of the tubular portion of the yokemay be moved to hold the yoke and the parts carried thereby in position.This yoke may also be formed of pressed sheet-metal and in order toprovide a simple and inexpensive method of mounting the connecting railsthereon permitting ready assemblage and affording ample strength, Isecure within each of the arms of the yoke a body of metal which servesas a support for a stud. The connecting rails may be angular in crosssection and may be out to the proper size from long lengths; this beingdone it is only necessary to provide an opening in the web of the railfor the stud the end of which may be threaded to receive a nut by whichthe rail Specification of Letters Patent.

is held down upon the yoke securely. Between the rails I provide a coverplate closing the upper open side of the yoke to prevent dust fromentering into and filling the interior of the yoke and pedestal.

My improved seat frame will be more readily understood by reference tothe accompanying drawings which show the preferred embodiment thereofand in which Figure 1 is an elevation of the seat-frame partly insection, Fig. 2 is a similar view at right angles to that of Fig. 1, thesection of the end of the yoke being on line 22 of Fig. 1, Fig. 3 is atop view, and Figs. 41 to 7 are detail views showing modifications, thesection line of Fig. 7 being the line 77 of Fig. 6.

Referring to these drawings, 1 indicates the pedestal and 2 the yokesupporting the connecting rails 3 3 on which the seat cushion is adaptedto be mounted in any usual or suitable manner. The pedestal 1 is formedof pressed sheet-metal and at its lower edge is provided with anintegral flange 4 perforated to receive screws 5 by which it may besecured to the floor. The yoke 2 is also formed of pressed sheet-metaland on its lower side at about the middle a tubular extension 6 is drawnout, this portion being of the same dimensions as the upper end of thepedestal 1.

In order to hold the yoke securely upon the pedestal, I secure withinthe upper end of the pedestal a metallic band or collar 7. This collarmay be secured o the pedestal by brazing in such position that abouthalf of its width extends beyond the end of the pedestalo As thusconstructed the extension 6 of the yoke its over the collar 7, its edgeresting upon the upper edge of the pedestal, and is held by the collarsecurely in position. By making the pedestal in two parts in thismanner, the parts may be manufactured in large numbers, and when a seatis to be assembled, the coacting edges of one or both of these parts maybe trimmed so that the completed seat will be of the desired height. Theyoke 2 is so shaped that the ends of the arms are displaced laterallyfrom the axis of the pedestal so that the latter will be located somedistance in from the end of the seat. Each of the arms of the yokesupports one end of one of the connecting rails 3.

In the end of each arm of the yoke is a body of metal 8 conforminggenerally in shape to the interior of the arm and therefore held therebyagainst displacement. In order to prevent any movement whatever of thebodies 8, independently of yoke 2, additional securing devices may beemployed. In Figs. 1 and 2 I have shown for this purpose a collar 9fitting snugly within an open; ing in the body 8 and the material of thesides of the yoke is sunk into the ends of this collar to hold itagainst movement. In Figs. 4 and 5 the metal block 8 is shown secured bya screw 10 which extends through a perforation in the yoke 2 and into athreaded opening in the block. In Figs. 6 and 7 depressions are formedin the sides of the block 8 and the metal of the yoke is driven intothese depressions, as indicated at 11. Any one of these methods may beemployed for holding block 8 securely in position.

Extending upward vertically from the upper surface of block 8 is a stud12 this stud may be threaded throughout its length and may be screwedinto a threaded opening in the top of the block. The rails 3 are angularin cross section and may be of the form shown in Fig. 1 or that shown inFig. 4, and are cut to the length necessary for the desired seat. Thebottom flanges which are adapted to rest u on the upper surface of theblock 8 are per orated to correspond with the studs 12 and when therails are in position holding nuts 13 and jam nuts 14 are screwed on theends of the studs and down upon the flanges of the rails to hold thelatter securely upon the blocks.

The yokes 2 as thus formed by pressing sheet-metal to the desiredconfiguration, are open at the top between the blocks 8 in the endsthereof and in order to prevent the collection of dust within thepedestal I provide a cover plate 15 fitting down upon the top of theyoke and closing the space between the sides of the latter and therails. This cover plate is secured in position preferably by flangingthe upper edges of the sides of the yoke as indicated at 16 and turningthe edges of the cover plate over this flange.

A seat-frame constructed in this manner, besides being of symmetricaland ornamental appearance, is simple and inexpensive, the parts can bequickly and easily assembled and the frame as a Whole is quite strongenough to withstand the strain and jars to which it is subjected in use.

While the studs 12 and the nuts coacting therewith are preferred as ameans for holding the rails in the bodies of metal 8-, I do not wish tobe understood as limited to the use of this particular securing deviceexcept by the terms of the claims appended hereto, as other securingmeans may be employed, such as a headed bolt extending through theflange of the rail with its threaded end entering a threaded opening inthe body 8.

What I claim is:

1. The combination of a seat-frame consisting of sheet-metal pressedinto form and having a base and arms at the upper end of said base, saidarms being generally U-shaped in transverse cross-section, connectingrails resting upon the outer ends of said arms, studs extending upwardlyfrom said arms through openings in said rails and means Within theU-shaped part for securing said studs to said arms, substantially asdescribed.

2. A seat-frame having arms at its upper end, bodies of metal fillingthe ends of said arms, connecting rails, and means securing said railsto said bodies of metal, substantially as described.

3. A seat-frame having arms at its upper end, bodies of metal withinsaid arms at their outer ends, connecting rails, and means securing saidrails to'said bodies of metal, substantially as set forth.

4. A seat-frame having a hollow yokeshaped upper end, bodies of metalWithin said yoke-shaped portion, means securing said bodies in positionand studs carried by said bodies, substantially as described.

5. A seat-frame having a hollow yokeshaped upper end, bodies of metalsecured within said yoke-shaped portion and means for securing rails tosaid bodies, substantially as described.

6. A seat-frame comprising a pedestal, a yoke detachably secured thereonand having forwardly and rearwardly extending arms, a block of metalsecured in each of said arms, a stud projecting upwardly from each ofsaid blocks, rails resting on each of said blocks with the stud thereonextending through an opening in the rail and nuts on the studs holdingthe rails in position, substantially as described.

7. A hollow sheet-metal seat-frame having forwardly and rearwardlyextending arms at the upper end thereof, supports for rails at the endsof said arms, said frame being open at the top, and a cover plateclosing the opening to the interior of the seat-frame at the top thereofbetween said rails, substantially as set forth.

8. A hollow metallic seat-frame having a yoke-shaped upper end, supportsfor rails at the ends of said yoke-shaped portion,

flanges on the sides of said yoke-shaped por,-'

tion and a cover-plate coacting with said flanges to secure the plateupon the top of the seat-frame, substantially as described.
